Let V be the volume of the threedimensional structure bounded by the region 0≤z≤1−x^2−y^2. If V=a/bπ, where a and b are positive coprime integers, what is a+b?

could someone please point me in the right direction?

Ahh  another Brilliant challenge. Maybe you're participating at the wrong level.

How do you know anyways?

Are you just going to assume that any problem I ask for help on is from "Brilliant"?
